Question

团队，我正在努力从VBA代码中提取zip文件，但收到错误，这是我的代码

Sub Un_Zip_File()
Dim flname As String
Call PathCall
flname = Dir(impathn & "Transactions*.zip")
Call PathCall
Call UnZip_File(impathn, flname)
End Sub

Sub UnZip_File(strTargetPath As String, fname As Variant)
Dim oApp As Object, FSOobj As Object
Dim FileNameFolder As Variant

If Right(strTargetPath, 1) <> Application.PathSeparator Then
strTargetPath = strTargetPath & Application.PathSeparator
End If

FileNameFolder = strTargetPath

'destination folder if it does not exist
Set FSOobj = CreateObject("Scripting.FilesystemObject")
If FSOobj.FolderExists(FileNameFolder) = False Then
FSOobj.CreateFolder FileNameFolder
End If

Set oApp = CreateObject("Shell.Application")
oApp.Namespace(FileNameFolder).CopyHere oApp.Namespace(fname).Items

Set oApp = Nothing
Set FSOobj = Nothing
Set FileNameFolder = Nothing

End Sub

当我运行Un_zip_file宏时，我在调试移动后收到错误“对象变量或未设置块变量”

oApp.Namespace(FileNameFolder).CopyHere oApp.Namespace(fname).Items

这是另一个如何解压缩文件的示例。
宏将zip文件解压缩到固定文件夹"C:\test\"

Sub Unzip()
    Dim FSO As Object
    Dim oApp As Object
    Dim Fname As Variant
    Dim FileNameFolder As Variant
    Dim DefPath As String

    Fname = Application.GetOpenFilename(filefilter:="Zip Files (*.zip), *.zip", _
                                        MultiSelect:=False)
    If Fname = False Then
        'Do nothing
    Else
        'Destination folder
        DefPath = "C:\test\"    ' Change to your path / variable
        If Right(DefPath, 1) <> "\" Then
            DefPath = DefPath & "\"
        End If

        FileNameFolder = DefPath

        '        'Delete all the files in the folder DefPath first if you want
        '        On Error Resume Next
        '        Kill DefPath & "*.*"
        '        On Error GoTo 0

        'Extract the files into the Destination folder
        Set oApp = CreateObject("Shell.Application")
        oApp.Namespace(FileNameFolder).CopyHere oApp.Namespace(Fname).items

        MsgBox "You find the files here: " & FileNameFolder

        On Error Resume Next
        Set FSO = CreateObject("scripting.filesystemobject")
        FSO.deletefolder Environ("Temp") & "\Temporary Directory*", True
    End If
End Sub

Answer 2

为避免出现消息错误：

1-每个“ \”更改“ /”

unzipToPath= Replace(unzipToPath, "/", "\\")

zippedFileFullName= Replace(zippedFileFullName, "/", "\\")

2-使用double（（将参数如下：

ShellApp.Namespace((unzipToPath)).CopyHere
ShellApp.Namespace((zippedFileFullName)).Items

Answer 3

我有完全相同的问题，但在MS Word中，尝试从.zip文件夹中提取文件。经过大量的实验和测试后，我发现后期绑定对象没有正确初始化，当我使用TypeName函数测试它们时，通常＆＃34;没有＆＃34;。

我在Windows 10和旧的Windows XP计算机上测试了我的代码，结果相同。我的所有测试都在Excel 2007和Excel 2016中进行。

将代码从后期绑定更改为早期绑定解决了该问题。

延迟绑定使用CreateObject函数初始化Shell.Application库中的对象。早期绑定需要为＆＃34; Microsoft Shell控件和自动化＆＃34;设置引用。您项目中的库。

要设置参考，请执行以下操作：在VBA IDE中，使用“工具”菜单打开“引用”对话框。滚动可用参考列表，直到找到＆＃34; Microsoft Shell控件和自动化＆＃34;输入，然后单击复选框以选择该库，因此： The VBA References dialog, showing the "Microsoft Shell Controls and Automation" library after adding it to your project.

在网络上的其他地方找到了，并认为这可能对您有帮助...

Sub UnzipAFile(zippedFileFullName As Variant, unzipToPath As Variant)

Dim ShellApp As Object

'Copy the files & folders from the zip into a folder
Set ShellApp = CreateObject("Shell.Application")
On Error Resume Next
ShellApp.Namespace(unzipToPath).CopyHere ShellApp.Namespace(zippedFileFullName).Items
On Error GoTo 0
End Sub

Answer 5

我有同样的错误“对象变量或未设置块变量”。

通过添加对“ Microsoft Shell控件和自动化”-Shell32.dll的引用来解决。然后按此顺序定义和使用Shell对象。

不要跳过任何这些步骤。我还在此page中发布了完整的代码。

Dim wShApp As Shell

Set wShApp = CreateObject("Shell.Application")
Set objZipItems = wShApp.Namespace(zipFileName).items  

wShApp.Namespace(unZipFolderName).CopyHere objZipItems

通过Excel VBA代码解压缩文件
